Combining ORAM with PIR to Minimize Bandwidth Costs
2015
Proceedings of the 5th ACM Conference on Data and Application Security and Privacy - CODASPY '15
Cloud computing allows customers to outsource the burden of data management and benefit from economy of scale, but privacy concerns limit its reach. Even if the stored data are encrypted, access patterns may leak valuable information. Oblivious RAM (ORAM) protocols guarantee full access pattern privacy, but even the most efficient ORAMs proposed to date incur large bandwidth costs. We combine Private Information Retrieval (PIR) techniques with the most bandwidth-efficient existing ORAM scheme
